7 things to check before fixing a draughty home
Before buying new windows or another heater, take a closer look at the problem you’re trying to solve.
There’s a particular kind of frustration in a room that never feels quite comfortable. You turn up the heat, move your chair, then start browsing expensive upgrades. Our suggestion: pause the shopping and make a short list of what you’ve actually noticed. A better description of the problem is a useful first step.
1. Name the uncomfortable spot
Is it the whole room, the seat beside a window, or the floor near a door? Note where and when you feel the draught. Take photos of visible gaps. This gives you something concrete to discuss with a landlord or contractor instead of a vague request to ‘make it warmer’.
2. Separate fixed gaps from moving parts
Caulk and weatherstripping have different jobs. Caulk is used at stationary joints; weatherstripping suits moving parts such as opening windows and doors. Identifying the location matters before choosing a material.

3. Don’t seal every opening you find
A home also needs ventilation. The South Carolina Energy Office recommends assessing ventilation needs before sealing air leaks. An opening you don’t understand is a reason to ask a qualified professional—not an invitation to fill it.

4. Look for moisture problems first
Water damage deserves attention before cosmetic improvements. The Department of Energy gives the example of repairing a leaking roof before insulating the attic: otherwise, the leak can undermine the new insulation.

5. Think beyond the window
Whole-house weatherization considers the building shell, heating and cooling equipment, and other systems together. A new window is only one possible intervention. Ask what evidence supports a proposed fix before committing to it.

6. Ask what safety checks are included
Professional weatherization can include combustion-appliance testing, ventilation checks and moisture assessment. If fuel-burning appliances are involved, ask how the work will preserve safe ventilation rather than treating comfort as the only goal.

7. Make the next step small and specific
Finish with one action: send the landlord your photos, ask for an assessment, or request a clearly itemized quote. You don’t have to solve the entire house this weekend. You do need to know what the first job is meant to accomplish.
